As of 31 December 2022

Slovenia has a single reactor operating at Krško, about 40 km northeast of Zagreb. It is a two-loop Westinghouse PWR with a net capacity of 688 MWe.

The plant’s operating company Nuklearna Elektrarna Krško (NEK) is jointly owned by Slovenian state-owned company Gen-Energija and Croatian state-owned company Hrvatska Elektroprivreda (HEP).

A decision-in-principle on a further unit at Krško – referred to as JEK 2 – was expected to be made in August 2023, with a decision on its construction in 2027.

In January 2023, the Ministry of the Environment approved a 20-year extension of Krško's operating lifetime. In April 2023 a used fuel dry storage facility was commissioned at Krško.
